目的:考察甲壳素对小儿健脾合剂水提取液澄清效果。方法:采用L9(34)正交试验法优选最佳澄清工艺条件并检测自然沉降法、醇沉淀法和甲壳素澄清法后小儿健脾合剂的相对密度,总固体物质量分数。结果:最佳澄清工艺条件为(A3B2C1):清膏温度50℃,1%甲壳素盐酸溶液用量为3%,搅拌时间25min。甲壳素澄清法澄清前后相对密度、总固体物质量分数优于自然沉降法和乙醇沉淀法。结论:甲壳素澄清法工艺简单、澄清效果满意,适用于小儿健脾合剂的澄清。
Objective: To investigate the clarification effect of chitin on children Jianpi Mixture water extract. Methods: The optimum conditions of clarification were optimized by L9 (34) orthogonal test and the relative density and the total solid content of Pedoque Spleen Mixture after natural sedimentation, alcohol precipitation and chitin clarification were tested. Results: The optimum conditions of clarification were (A3B2C1): the clearing temperature was 50 ℃, the dosage of 1% chitin hydrochloride solution was 3% and the stirring time was 25min. Chitin clarification method to clarify the relative density before and after, the total solid mass fraction better than natural sedimentation and ethanol precipitation. Conclusion: The process of chitin clarification is simple and the clarification effect is satisfactory. It is suitable for the clarification of pediatric Jianpi mixture.
